3,4-Diaminotoluene Usage And Synthesis
Chemical Properties
Off-white small blocks
Uses
5-Methylbenzotriazole intermediate.
Uses
4-Methyl-o-phenylenediamine was employed as chromogenic reagent in the spectrophotometric determination of selenium(IV). It was used in the synthesis of an asymmetrical tetradentate Schiff base via condensation with dehydroacetic acid and salicylic aldehyde.
Synthesis Reference(s)
Tetrahedron Letters, 42, p. 2277, 2001 DOI: 10.1016/S0040-4039(01)00163-0
General Description
A colorless to brownish purple crystalline solid. Toxic by ingestion and inhalation and an irritant to skin and eyes. Soluble in water, alcohol and ether. Decomposes to emit toxic oxides of nitrogen when heated to high temperature. Used in making dyes.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
3,4-Diaminotoluene neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Fire Hazard
Flash point data for 3,4-Diaminotoluene are not available. 3,4-Diaminotoluene is probably combustible.
